No Solution

Step-by-step explanation:

ln x - ln (x + 2) = 4             restrictions: x > 0  and  x + 2 > 0   →    x > 0

ln = 4

= e⁴

x = e⁴ (x + 2)

x = 54.5982 (x + 2)

x = 54.5982x + 109.1964

- 53.5982x = 109.1964

x =

x = -2.0373

-2.0373 is not greater than 0 so is not valid

2.1972

Step-by-step explanation:

eˣ = 9

ln eˣ = ln 9

   x = ln 9

   x ≈ 2.1972

Step-by-step explanation:

log₂ (3x - 4) = -1

        3x - 4 = 2⁻¹

         3x - 4 =

              +4   +4

          3x     =

          3x     =

            x =
